Apple patents method to toggle wireless data retransmission on or off
Apple has filed a patent application for a method that allows a device to turn a specific data check feature on or off based on instructions from the network. The system uses control signals to determine when the device should confirm if it received data correctly or if the network should resend it. The filing notes this could be useful for Internet of Things devices or satellite connections.
In the filing’s own words
Systems and methods for hybrid automatic repeat request (HARQ) feedback enablement/disablement are discussed herein. A user equipment (UE) may receive, from a network, configuration information comprising an indication for the UE to use HARQ enablement information of a downlink control information (DCI), receive the DCI comprising the HARQ enablement information, and use the HARQ enablement information of the DCI to determine one or more HARQ enablement statuses for corresponding one or more HARQ processes for communicating HARQ acknowledgement (HARQ-ACK) information from the UE to the network or for one or more TBs using such HARQ processes. A network device may send configuration information to the UE comprising an indication for the UE to use HARQ enablement information of a DCI and send the UE the DCI comprising the HARQ enablement information. Applicable contexts for methods disclosed herein may include, for example, Internet of Things (IoT) and/or non-terrestrial network (NTN) contexts.
What exactly they claim (claim 1)
1. A method of a user equipment (UE), comprising: receiving, from a network, configuration information comprising an indication for the UE to use hybrid automatic repeat request (HARQ) enablement information of a downlink control information (DCI); receiving, from the network, the DCI comprising the HARQ enablement information; and using the HARQ enablement information of the DCI to determine one or more HARQ enablement statuses for corresponding one or more HARQ processes for communicating HARQ acknowledgement (HARQ-ACK) information from the UE to the network.
